Once, my friends Hannah and Trish were spending the night at my house, and we were all sleeping on the floor, and we saw what looked like a little boy in a striped shirt run down the hall and back. I swear, I do not have a brother and there were no boys in the house that night. Also, once, Hannah and I were playing with my keyboard (piano kind, not computer kind) and afterward we left the room and I was the last one out, and I saw that the keboard was off. A while later, we heard music coming from the room that the keyboard was in, and when we went in to the room the keyboard was on and playing one of the demo songs.
